The safe and reliable transmission of relay protection signal is essential to the normal operation of relay protection device. Based on the characteristics of the protection signal transmission, this paper proposes a method to model the real time failure rate of the protection communication channel introduced by the communication latency and bit error. First of all, by using the decision tree method...
Time-interleaved analog-to-digital converters (TIADCs) are essential in wide-band communication systems for providing high-speed data conversion. However, TIADCs are sensitive to the sample time mismatch, which results in significantly degraded performance. A new calibration technique is proposed to minimize sample time mismatches among interleaved channels. Correlation between adjacent channels based...
This paper presents two multichannel non-persistent CSMA (M-np-CSMA) MAC schemes using Simple Reinforcement Learning and State-Action-Reward-State-Action (SARSA) learning respectively for distributed cognitive radio networks. The two learning schemes both use reinforcement learning to help the users learn the environment and historical transmissions. Compared with M-np-CSMA MAC protocol with random...
This paper deals with the problem of robust stability analysis for uncertain stochastic neural networks with time-varying delay. Based on the Lyapunov-Krasovskii functional theory and the free-weighting matrices method, the delay-dependent criteria are proposed in terms of linear matrix inequality (LMI). Two examples are given to show the less conservativeness of the obtained conditions.
Today's file sharing networks are creating potential security problems to enterprise networks, i.e., the leakage of confidential documents. In order to prevent such leakage, we propose the Data Leakage Prevention System (DLPS) which is applied at the entrance of the enterprise network to filter out the outgoing sensitive information. The DLPS is based on a content scanning engine which defines a new...
